Participants at the Shakertown Symposium represented the five major human systems that serve troubled youth: education, mental health, social welfare, juvenile justice, and health. The papers focused on youth problems from the perspective of each system, the causes of antisocial behavior, the resources and strategies each system offers in serving troubled youth, the effectiveness of the services, the strategies each system could contribute in a comprehensive network of integrated services, the barriers to developing a comprehensive network of systems, and actions that would help achieve the goal of comprehensive integrated systems. Participants agreed on the need for all systems to define new collaborative roles for helping professionals, collaborative efforts to develop comprehensive and community-based systems of care that range from prevention through long-term treatment and management, collaboration and integration of functions among all child service agencies at the Federal and State as well as local levels, and increased Federal and State funding of local interagency and interdisciplinary research and demonstration projects.
